[Best Tool Asset Store Award] Amplify Shader Editor - Node-based Shader Creation Tool

Hi all

I am looking for a video tutorial or a written tutorial regarding Custom Render Textures within ASE

I would like to use a caustics texture generated out of the water ripple normals and project it to the water ground with a decal projector, so the caustics change according the water ripple normals.

Does anyone know of a tutorial describing such a process?

Thanks in advance,
Phil

 

That error gone after restarting Unity. But some times appear again.

 

Hello Everyone!

So thanks to ASE, I am now able do use Custom Render Textures, and this opens a LOT of opportunities for me (I am currently working on a real time GI thanks to it).

However, while it works great, I have a performance problem, that is very likely due to a bug.

I am using a 3D CRT right now, but the resolution Z (or W) makes the setpass draw calls skyrocket! Even in the inspector, be it in play mode or not. Here are some screenshots I made.

Is it a bug from ASE? Can it be resolved?

Anyway, keep up the good work everyone!

 

Not sure if this is the right place to ask, but I was wondering if anyone else was having any success combining matcaps with normal maps. It works perfectly in Shader Forge, but in ASE the normal map affects the diffuse but not the matcap:

(Please ignore the fact that I linked the matcap to albedo rather than emission in ASE)

 

Hi,

I'm trying to follow this tutorial (which is for Unity Shader Graph) with Amplify Shader Editor. I noticed that Amplify does not seem to have any nodes for generating Perlin Noise and Voronoi Noise procedurally. Those two kinds of noise are very useful for various effects (as shown in the tutorial) so it would be nice to have them as functions, rather than resorting to a noise texture.

Does Amplify Shader Editor have perlin and voronoi noise generation built-in somewhere?

 

I went on ahead and created the voronoi node myself, based on the open-source code provided by Unity ShaderGraph.

Here's the "custom expression" code:

Code (CSharp):

1. float2 g = floor(UV * CellDensity);
2. float2 f = frac(UV * CellDensity);
3. float t = 8.0;
4. float3 res = float3(8.0, 0.0, 0.0);
5. float r = 0.0;
6. for(int y=-1; y<=1; y++)
7. {
8.     for(int x=-1; x<=1; x++)
9.     {
10.         float2 lattice = float2(x,y);
11.         float2 iUV = lattice + g;
12.      
13.         float2x2 m = float2x2(15.27, 47.63, 99.41, 89.98);
14.         iUV = frac(sin(mul(iUV, m)) * 46839.32);
15.         float2 offset = float2(sin(iUV.y*+AngleOffset)*0.5+0.5, cos(iUV.x*AngleOffset)*0.5+0.5);
16.         float d = distance(lattice + offset, f);
17.         if(d < res.x)
18.         {
19.             res = float3(d, offset.x, offset.y);
20.             r = res.x;
21.             Cells = res.y;
22.         }
23.     }
24. }
25. return r;

How to use it:

1. Create a Custom Expression node
2. Copy-paste above code into the "Code" text field of the node
3. Under "Inputs", create the following:
   

I hope somebody will find this useful.

 

I think you need to connect the normal map tex to the World Normal > Normal input in order to "perturb" the normals used for matcap.

 

Hi everyone,

I have a qusetion on Amplify editor.
How do I create a node like "Matrix2X2" or "Matrix construction"?
even if I can editor code a new node for Matrix2X2?
ex:"Matrix construction" on Unity Shader Graph editor window.

 

Hi, everybody. Using LWRP + Android

Can't be easy Shader to Amplify analogue "SimpleLit" from Unity. Shader is obtained on many more slowly.

That is, I do "SampleTexture" and all.

Difference in FPS:
- Unity SimpleLit: 59
- Amplify Lightweight PBR: 37

Maybe it's worth your asset to use the functions in "Packages/com.unity.render-pipelines.lightweight/Shaders/".

Need mobile oprimization.

 

Hello, although we have no specific tutorial or sample for a caustics effect I'll register this as a suggestion for the developers to consider for a future sample.

Regarding custom render texture, we do provide a sample that could help you, you can find it within the CustomRTRain folder, it comes packed as a unity package for compatibility reasons as it can only be used in Unity 2017 and above.

Hey there, can you ensure that you're using the latest version from our website?

If you're on the latest version, could you provide a sample with the issue present as we're unable to replicate this behavior?

Hello, and thanks!

I'm not entirely sure but it doesn't seem likely that ASE is at fault here, since Unity should be calculating the render textures for each layer of the 3D CRT, which in turn makes sense that the drawcall count increases accordingly.

In any case, could you please share a sample to support@amplify.pt with additional details regarding how we could test this without having a 3D CRT?

Thank you for sharing, would you like to contribute this to our package?

More information here!

Hello, you may create your own nodes for ASE, you can find more information regarding this in our node API.
Also, be sure to check our Matrix Operators for a reference to all out currently available nodes.

Hey there, the comparison made wasn't correct as you're comparing a PBR lighting model with a simple one.
We would suggest that you use the LW Unlit template with the Blinn-Phong Light shader function that we provide.

Also, please refrain from posting questions to both our support email and to this thread, we'd rather if you just choose whichever you prefer, thanks!

 

That worked beautifully, thanks a lot.

 

I'm a bit lost trying to get multi pass shaders to work. I found the template and imported it but don't know how to edit it or add more passes.

I would really like to make a fur shader where I can increase the number of shells and offset them or change the clipping values in the shader rather than manually make lots of objects with lots of materials.

Thanks

 

1. I'm interested in both the Amplify Shader Editor and Amplify Occlusion and I'm not sure which one to get (or both). Are these assets intended to go together and do they compliment each other? Is it something like Unity's Post-Processing stack where you can include the Amplify Occlusion asset in the pipeline?
2. I am currently using Unity's Post-Processing stack for all my projects, is this intended to be a replacement for that or does it integrate?
3. In the store description it lists "Volumetric Pixelize by Raphael Ernaelsten" under Samples, is there some resource where I can find out more about what that is?

 

I was trying to make tinted shadows and came across this post which covers exactly that: http://amplify.pt/forum/viewtopic.php?f=23&t=622
To my surprise, it doesn't work for me. I tried creating a new project in case that was the problem, but that's not it. There must be something I should have done that I'm missing, but I don't know what. This is the as I copied it from the mentioned thread:


Instead of blending nicely as a shadow, the Lerp blends the textures as if the float went directly into de Alpha value. It's sa if the Light Attenuation part didn't exist at all.

 

Hello, we have an example and guide available in our Wiki Manual specific for setting up multi-pass shaders, and also offer a sample within the ASE package by the name of MultiPassDistortion.

To edit the shader code itself you must use a text editor, you can quickly open your current shader by pressing this convenient button:



Please be aware that you need to have some programming and shader knowledge in order to take advantage of this feature!

Hello, thank you for your interest!

1- Both have entirely different scopes; the Amplify Shader Editor is a tool that allows you to create shaders, including post-processing ones, whereas Amplify Occlusion is simply an image effect. Amplify Occlusion makes use of the PPS2 in Unity 2018.3 for supporting the LW and HD pipelines, we're currently investigating how we can add support for Unity 2019 as well.

2 - Neither asset is a replacement for the stack. Amplify Occlusion may be used together with the PPS as an alternative to Unity's occlusion solution as it presents a different technique, which is visually more accurate and flexible, while still being very performant. Do note that it's not yet compatible with Unity 2019.

3 - This is a community contribution that was kindly submitted by Raphael Ernaelsten, more information inlcuding a public download link for the sample here.

Hello, can you share which specific Unity and ASE versions you're currently using?

 

Thanks for the reply Borba, so is the workflow;
Edit the template in a text editor > import to ASE > Make a new shader with the new template > edit shader as normal in ASE?

What's your SRP Lightweight version?

 

Whoops, my Unity version was completely out of date. Thanks, it works now. Sorry for the inconvenience.

 

You may either use one of the ones we offer as a base ( simply duplicate it and rename / edit the duplicated file ) or create one outside of the project then import it into Unity.

When you're done editing your template, be sure to save it in your text editor and when going back to Unity allow it enough time to reload the asset, then you may select the Template via the Shader Type drop-down list in your shader's main output node.

Please be aware that, if you have any shaders using a template that has been modified, they should be manually recompiled.

 

Hi! I need help.

LWRP. Mobile optimization.

Please tell me the best treatment option distance of the object from the camera? That is, I want something like the LOD, if the object is far away, it appears just texture, if close texture + reflection + shadow.

And another question, why if I use "Compare A > B", etc., you first go to the calculations for all the results and then displays one of the results? And not separately depending on comparison, there is a calculation? It turns out not optimized!

For example:

if (...) {

calculate1

variant1

}

else {

calculate2

variant2

}

 

Hello, the first question regarding LOD setup is outside of the scope of our support, so I'm afraid I can't offer much assistance in regards to that, apologies for the inconvenience.

Regarding your second question, please rest assured that we take great care in ensuring that the generated code is optimized, and also that the shader compiler is smart enough to only compile what it needs, so it does not generate additional instructions in this type of situations.

The way you can test this is by compiling the shader and checking the instruction count, you'll notice that the compiled code will be optimized even though it in certain cases it may not seem as such.

Hello Borba, Is there any progress made regarding to this Normal Issue? Hope everything is on track so far.
It has already been messy that we got a lot of fbx having this issue after imported to U3D 2018 LWRP, which cost us lots of extra manual adjustment to get rid of the glitches...for some of them we just improvised to switch back to LWRP/SimpleLit.

 

Hello, I can confirm that your reported issue is currently in our suport queue, our developer will tackle it as soon as possible, we apologize for the inconvenience.

 

Hi,
I am trying to use the CustomOutlineToon shader in the example folder. It's working fine with the example models. But whenever I import a model and apply the shader, it has some weird effects. Anyone knows how to fix this?

Thanks.

 

Hey, I have just started learning ASE and it's amazing!

I am working on a custom grass shader that uses Noise and Panner to animate the vertices. I am trying to make the Panner direction based on a global value from a game object in the scene, but I had no success so far.

I think I need to convert the Y rotation of the global value to X and Y of the panner and I don't know how to do that.
Any help would be appreciated, I am still learning and I am missing a lot of knowledge but so far it is fun.

Here is how part of the shader looks like, for context:

 

Hey, would be great if we could test that model. Are the vertices welded?

Have you tried the Rotator node?

Thanks!

 

This is happening with any imported model even with a simple sphere. However with unity's default prefabs (cube, sphere etc), it's working fine. I've tried exporting models from both maya and blender, default settings.

 

We would be happy to check it, can you send us one of the problematic ones?

 

Thanks! I've attached a model.

 

I believe you'll have to change the outline mode to "Vertex Scale" if you want to keep the hard edges.



Alternatively, you can adjust the smoothing in Blender(assuming you are using blender), else the faces will be offset individually.

Unity also allows you to Calculate Normals instead of importing them.





Hope it helps, thanks!

 

HDRP 5.13 | amplify sh ed 1.6.7 | Unity 2019.2

Generates the following error when using HDSRPTemplates.unitypackage :

Shader error in 'Hidden/Templates/HDSRPLit': 'InitBuiltinData': cannot convert from 'struct PositionInputs' to 'float' at line 476 (on d3d11)


am I missing something?

 

Hello
Having some weird issues with normal maps and LWRP
The top one is an unlit shader not in LWRP
the bottom is the same shader in LWRP and amplifys LWRP unlit template
Normal map is imported as normal map and unpack normals is checked.
Am I doing something wrong?

Cheers

 

Plz help. Im looking for something to replace this node:
https://docs.unity3d.com/Packages/com.unity.shadergraph@5.3/manual/Sampler-State-Node.html
Actually Im trying to use:

Code (CSharp):

1. SAMPLE_TEXTURE2D(_MainTex, sampler_MainTex, uv);

In custom expression. What should I put into _MainTex and what into sampler_MainTex?

 

Hello! Do you have the Normalize float function with the Min Max parameter? or you need to add yourself?

Example:

public static float Normalize(this int value, float min, float max)

        {



            return (Mathf.Clamp(value, min, max) - min) / (max - min);



        }

 

Hello, we don't officially support Unity Betas or Alphas, which is the case for 2019.2 and 2019.3 respectively.

As such, we recommend that you use the latest stable version with our editor, Unity 2019.1.3f1, together with the HDRP v5.13.

Hello, please send a sample together with your textures to support@amplify.pt while also referencing this post, thanks!

Hello, we don't offer any node comparable to that one but it's something that we're hoping to tackle as soon as possible. Could you share further details regarding what you're trying to do and why do you require the sampler state to be separated, so that we may provide any further insight?

Hey there, our Normalize node does not offer such parameters but you should be able to accomplish this through a Custom Expression node.

 

Thank you for your response. Nothing really require to use the sampler state for now. Im new in ASE so just trying to dig and compare with Shader Graph.

 

Hello,
Is it possible to create a shadow matte using ASE? Here's an explanation of what I mean by shadow matte:
https://docs.arnoldrenderer.com/display/A5AFMUG/Shadow+Matte
In my scene, I have
-a photographed image on a plane as a background plate
-a perpendicular 2D plane as a floor (shadow catcher)
- and a 3D object on the plane
I would like to see through the 2D floor plane to the background image while catching the shadow of the 3D object on the plane.
Perhaps something similar to the grab screen position / color example could be modified to work to catch shadows.
http://wiki.amplify.pt/index.php?title=Unity_Products:Amplify_Shader_Editor/Grab_Screen_Color

Any thoughts would be appreciated!

 

Hello! Transparency and shadows is a complicated matter to deal with due to rendering limitations present in most engines. Transparent materials are not meant to handle shadows as the shader is written in the transparent queue, but not in the depth buffer, so it's not accounted for by Unity's shadow pass.

A possible workaround, that would be far from perfect, would be to turn your transparent object into opaque and use a grab pass to try and simulate transparency on your own. For this you would also need to consider the Render Queue offset so that this object would be rendered after all other opaque objects.

Alternatively, if you're comfortable with shader programming, you could try setting up a custom shader through our templates system to handle this specific situation.

 

Hello,
I am looking for a simple way to controle multiple static switches (with the same keywords) at the same time directly in the material inspector. I don't know if the "Fetch" mode of the node can help in this but I wasn't able to make it work for what I want.
Will I need to use an external script for this?
Thank you

 

Hi, is it possible to create normals from a RGBA output instead of a Tex output? I've made a shader that works with my character creation system, so i need the normals to be generated at runtime from the texture combination(scars, skin detail, etc). Can you help me solve this issue?
Thanks.

 

Thanks! Using an opaque material and adjusting the Render Queue worked like a charm, I just had to dial down (subtract) a little from the grab pass emission so the shadows would show up better.

 

Please help me...

I'm using HDRP for my project and I would like to use Amplify
I'm currently using 4.10.0 version of HDRP and tried to use HDSRPTemplates as was described in the SRP Amplify Wiki
(since there is a chance I missed something:in a whole setted HDRP project, I downloaded the Amplify package and opened/imported the HDSRP templates)

there wasn't a SRP version of Amplify Shader in the "Create" option when I right-clicked... so I made a Amplfiy Surface Shader and changed the Shader Type to "HD Lit" and tried testing it but it didn' t work



By the way I just tried to put the Color node in Albedo........

I'm not sure I did anything wrong... would love some help

 

Hi,

Can the blend/depth/stencil options could be override on individual materials instead of creating a new copy of shader?

 

Hello, could you please provide additional information regarding what exactly do you want to use the static switches for, and what do you mean by controlling multiple switches?

Hello, you could try creating a new shader function based on our provided NormalCreate one, simply double click it to see how it's set up.

Hello, the HDSRPTemplates.unitypackage is meant for Unity 2019.1 and the new HD SRP 5.xx, since you're using the HD SRP 4.10 ( Unity 2018 ), you need to extract the HDSRPTemplates 4xx (Legacy).unitypackage.

We've noticed that the manual is slightly outdated and have proceeded to update this information, it's still present in the readme.txt included in the templates folder of the ASE package in any case.

Hello, yes it should be possible to set most of those parameters per material.

 

A bit hard to explain I hope this is clear enough:
I am making a terrain shader with splatmap, that would lets the users choose how many different materials they want to blend together, between 2 and 5.
For each option I would need to enable three Layered Blend nodes (for Albedos, Normals, MetalSmoothHeights) that have the corresponding amount of layers (2,3,4 or 5). But I can't find a way to enable them simultaneously (to switch between these different groups of three), using one single command in the inspector.
For now the only solution I found is to have a keyword enum for the number of Albedo layers, a keyword enum for the number of normal layers etc, wich results in three dropdown lists in the material inspector, for three values that need to be equal. Not very practical and it unnecessarely multiplies the amount of shader features.
In other words, I would like to use the same switch to change different things in the shader at the same time, but I am not sure if this is possible.

EDIT: I need this to optimize the material by disabling unused texture slots if for exemple, the user only wants to blend 2 or 3 different materials (using only some of the splatmap channels).

 

(sorry I can't edit my post anymore. here is my screen)

 

Hey,

Is there any way to know which camera (or more specifically, which target eye for VR) is currently rendering? I would love to create a shader that knows to use different UV offsets based on which camera/eye, that way I can have 1 material for both left and right eyes in our VR project. Its not using real 3d, but two panorama images with a proper offset, each rendered by a different eye. We have two cameras, one for the left eye and one for the right, two spheres, two materials, etc.

[Edit -- I'm aware this may not be possible. I don't really understand how multiple cameras rendering different eyes interact with shaders to begin with]

 

Thank you for the additional details! I believe that you can use the same keyword for different static switches, meaning that you won't need different keywords for Albedo, Normal, etc.
Also, if you want to change the keyword through the material inspector and only use one enum list simply disable the Material Toggle paramets for all the Static Switch nodes.

You can find additional information regarding the use of this node, such as how to change the keyword via code, in this post. Please let us know if the shared information helps!

Hello! According to the Unity Documentation, shaders expose the constant in-built variable ‘unity_StereoEyeIndex’ to allow for eye-dependent calculations, and you may access this in ASE by creating an Int node then setting it to Global and its variable mode to Fetch, so that the declaration is not registered on the shader:



Keep in mind that the value of "unity_StereoEyeIndex" is 0 for left-eye rendering, and 1 for right-eye rendering.
